[Pw_forum] PW taskgroups and a large run on a BG/P

[David Farrell]

I tried reducing nbnd, diago_david_ndim, mixing_ndim, and still no  
good. Memory issue seems to remain.

In my system I have set nosym = .true.  - so I would think the below  
wouldn't be the problem... or is this flag for a different symmetry  
operation?
